The 2008 NFL season was the 89th regular season of the National Football League, themed with the slogan "Believe in Now."

Super Bowl XLIII, the league's championship game, was at Raymond James Stadium in Tampa, Florida on February 1, 2009, with the Pittsburgh Steelers coming out victorious over the Arizona Cardinals 27–23 and winning their NFL-record sixth Vince Lombardi Trophy. Conversely, the Detroit Lions became the first NFL team with an imperfect season since the strike-shortened 1982 NFL season, finishing their season 0-16.

The regular season began on September 4 with the defending Super Bowl champion New York Giants defeating the Washington Redskins 16–7, and concluded with the 2009 Pro Bowl on February 8, 2009 in Honolulu.

In preseason games, the annual Pro Football Hall of Fame Game was played August 3 between the Indianapolis Colts and Washington Redskins, which aired on NBC. Washington won the game, 30–16. Other preseason highlights included the first game of the Toronto Series, which was played August 14 between the Buffalo Bills and the Pittsburgh Steelers at Toronto's Rogers Centre. The Bills won that game, 24–21.

The National Football League has enjoyed success in selling out many of their venues from season ticket sales alone. Out of 32 teams in the league, 24 claim to have waiting lists from under 1,000 people to over 150,000. For some fans, this means a wait not just of years, but decades. This is due mostly to the NFL's short window of play; there are only eight regular-season home games, forcing the most devoted fans into a desperate and sometimes costly search for a limited number of events.

Since 1973, the waiting lists have also had the by-product of preventing any home games of certain teams from being blacked out on local television. Home games must be sold out within 72 hours of kickoff before a telecast is allowed, and the longest waiting lists have ensured every home game of the applicable teams being locally televised. Prior to 1973, home games could not be locally televised even if they were sold out. Four teams have had the benefit of not seeing any blackouts at all since 1972.

Personal Seat Licenses (PSLs) is a license which grants the holder the right to buy season tickets for a particular team. PSLs were first used in the NFL by the expansion Carolina Panthers in 1993 to help finance their new stadium. Since that time, several teams have used the mechanism to finance new stadium projects including the Chicago Bears remodel of Soldier Field and more recently the Dallas Cowboys. The New York Jets and the New York Giants used PSL programs to finance the construction of the New Meadowlands Stadium, now MetLife Stadium.

The 2008 NFL Draft took place at Radio City Music Hall in New York City on April 26 and April 27, 2008. For the 29th consecutive year, ESPN televised the draft; the NFL Network also broadcast the event, its third year doing so. Of the 252 selections, 220 were regular selections in rounds one through seven, and 32 were compensatory selections, distributed among rounds three through seven. For the first time since the common draft began, no wide receiver was selected in the first round. Also, a record 34 trades were made during the draft itself.

The schedule for the draft was changed: day one began at 3:00 PM EDT (1900 UTC), instead of noon, and consisted of just two rounds. Day two began with round three at 10:00 AM EDT (1400 UTC), instead of 11:00 AM. Moreover, the time limits for day one selections were reduced, from 15 minutes to ten for first-round picks and from ten minutes to seven in the second. The limit remained five minutes for all picks in rounds three through seven.

The draft also marked the official debut of a new NFL shield logo, replacing the old shield logo which had been used since 1970, featuring eight white stars to represent each of the league's eight divisions, and a football rotated to the same angle as the one on the top of the Vince Lombardi Trophy given to the Super Bowl champion.
